Answer:
The force on the book is 250N.
Step-by-step explanation:
Newton's second law states that the equation for the force is:
In which m is the mass, in kilograms, and a is the acceleration, in m/s². F is the force measured in N.
In this question:
So
The force on the book is 250N.
Ok, there are two scenarios here.
1) It's a typo and "<K" should be written as "<J"
if that is the case, we can convert from degrees,minutes,seconds >> degrees like so
once calculated, we get 48.43 degrees.
scenario 2)
<k is the third angle in a right triangle
this would mean that <j + <K + 90 = 180
from the first example, we know that <J = 48.43 degrees
Therefor
48.43 + <k + 90 = 180
48.43 + 90 = 138.43
so
138.43 + <k = 180
Therefor, <K = 41.57 degrees
I really hope this helps!!:)
